Filed: 1925-08-19
Abstract: 263,074. Electrical Improvements, Ltd., and Grant, L. C. Aug. 19, 1925. Addition to 216,924. Thermionic modulating systems. - In a protective system for power lines in which wireless or wired-wireless methods are employed instead of field cables, as in the parent Specification, a control circuit F carrying a current which is proportional to the line current acts directly on the transmitting valves by electrostatic or electromagnetic means so as to modulate the high-frequency output in accordance with variations in the conditions of the circuit. As shown, the control circuit F is connected between a conducting shield F<3> arranged around each valve and the filament circuit. Electromagnetic control is obtained by connecting the control circuit to an inductance coil disposed adjacent to the valve so that the flow of electrons takes place within the magnetic field of the coil. Specifications 258,718, 261,115, [Class 40 (iv), Telephones &c.], and 262,842, [Class 38 (v), Electric switches &c.], are referred to.

Title: Process relating to the clarification of beer
IPC: C12H1/044
Filed: 1933-10-31
Abstract: Beer is clarified by means of metal foils or thin sheets of parchment, pasteboard, or compressed paper material of any kind, of substantially less than 0,4 mm. thickness.  The foils or sheets may be provided with a coating of resin, pitch, varnish, or other substance adapted to improve the taste of the beer, and thin sheets of card, pasteboard, or parchment provided with a metal coating may also be employed.  Metals specified as suitable are aluminium, silver, nickel, or any non-rusting metal.  The surface of the foils may be corrugated and/or roughened and perforated, especially with perforations of the kind found in rasp-sieves and produced by stamping.  Aluminium foil provided with creases or corrugations and made into rolls is mentioned as particularly suitable, but the foils or sheets may also be placed in the cask in the form of single short strips or as ribbon or wound on wire or sheet metal frames.  The chips are placed in the cask before filling, float to the surface when the beer is introduced, and sink down gradually afterwards, thus clarifying successive layers of the liquid.  The foils or sheets may be destroyed after use.

Title: Improvements in and connected with gas governors
IPC: G05D16/16
Filed: 1923-12-03
Abstract: 229,419. Simpson, J. F., and Peebles, W. C. Dec. 3, 1923. Pressure-regulating valves. - A station gas governor of the kind in which the load is increased as the valve opens is combined with a differential governor adapted to maintain a constant difference of pressure across the valve of the automatic governor. The automatic governor has a double beat valve CD connected bv a spindle B to a bell A subject to outlet pressure communicated through a pipe V1 controlled by a needle valve Y1. Two needle valves may be arranged in parallel a small one for fine adjustment when the combination is in use and a larger one when the automatic valve is being used as an ordinary governor. The valve spindle is continued upwards and is provided with a rack H engaging two toothed quadrants P, R. The quadrant R is formed on a lever T provided with a counterweight V for partly counterbalancing the, weight of the bell. The quadrant P is connected to a lever K weighted at L2 and provided with a curved track J on which runs a weighted trolley M. In the form shown the differential governor has a lift valve member K1 actuated by a counterweighted bell of equal area. The bell chamber is enclosed and connected by a pipe S1 controlled by a valve T1 to the outlet side of the second governor, so that this valve is controlled by the outlet pressure acting on the bell and the inlet pressure to the second governor acting on the back of the valve member. The valve members and seats may be fitted with co-operating relatively adjustable segments or ported sleeves. The bell of the second governor may be coupled to a recording apparatus, or with a variable additive mechanism for use as a meter. The outlet pressure of the second governor is arranged to be proportional to the amount of valve opening so that an ordinary pressure chart may be used for this purpose.

Filed: 1924-12-24
Abstract: 226,825. Westinghouse Electric & Manufacturing Co., (Assignees of Falknor, F. B.). Dec. 29, 1923, [Convention date]. Void [Published under Sect. 91 of the Act]. Thermionic heterodune receivers; audible reception of unmodulated continuous waves; thermionic modulating systems. - Continuous wave telegraph signals are received by the supersonic heterodyne method, the local oscillations being modulated at an audible frequency. As shown in Fig. 2, the signals are received on a tuned aerial to which is coupled a local oscillator 5 arranged to produce supersonic beats in the output circuit of the first detector 9. These beats are selected by a tuned circuit 13 and passed through an amplifier 14 to a second detector 16 having the phones 19 in its output circuit. The local oscillations are modulated at audible frequency owing to the provision of audio-frequency coupled circuits 26, 28 in the grid and plate circuits of the oscillator. The supersonic beats in the circuit 13 are thus modulated at audible frequency, and the second detector 16 enables this audible frequency to be heard in th phones. The modulation may alternatively be produced by a buzzer arranged to make and break the grid circuit of the oscillator 5 at audible frequency.

Title: Improvements in or relating to the method of and apparatus for the production or generation of sounds or tones
IPC: G10H5/08
Filed: 1925-12-08
Abstract: 244,133. Goldberg & S÷hne Ges., M. J. Dec. 8, 1924, [Convention date]. Musical instruments with sonorous plates.- Two thermionic oscillation generators 2, 4 are coupled to a detecting valve 5 and the resultant vibrations are rendered audible by a sound generator 11. The system is utilized as a musical instrument by providing an aerial 1 the operator moving his hand adjacent to the aerial to obtain the required note. A number of aerials may be provided so that a number of tones are generated simultaneously and by adjustment of the dimensions the operator may finger the instrument as he would play a violin, a bass viol, &c. The low frequency oscillations may be amplified by a system of thermionic valves. The operator may control the volume of sound by means of a shunt resistance across the sound generator 11, or by a resistance in the filament circuit of one of the valves. Alternatively the filament heating through coupling coil 96, Fig. 11, from the oscillating circuit of a generator 100 may be regulated by the operator influencing aerial 92 in the same manner as aerial 1. In a modification the generator 100 is arranged to control the grid potential of an amplifying valve. A switch may be provided to short-circuit or open the circuit of the sound generator of a particular tone or may interrupt the filament heating current. The switch may be controlled by a similar aerial and oscillation generator to that used for controlling the volume of sound. Various assemblages of impedances may be arranged in series or parallel with the transformers or sound generator to correct for resonance and similar arrangements may be employed to vary the colour or timbre of the tone. Alternatively the valve characteristics may be varied to produce these effects. In a modification, Fig. 26, the tone colour variation is effectedby varying the saturation of a transformer 172 in the anode circuit of one of the valves by means of an auxiliary winding 175. Arrangements are also described for simultaneously producing two and four tones by using a corresponding number of aerials with separate generators.
